Eliot's line after the gunfight, "I don't [like guns]. Never said I couldn't use 'em.", is awfully close to Tom Selleck's line, as Matthew Quigley, in 1990's Quigley Down Under (1990): "I said I never had much use for [a pistol]. Never said I didn't know how to use it."
Nate's alias, "Lionel Whitney," is the same name as Jeff Goldblum's character from the TV series Tenspeed and Brown Shoe (1980)
Damien Moreau's repeatedly asking Nate who he is echoes the "Who are those guys?" refrain in Butch Cassidy & the Sundance Kid.
There is a reference to a small European country named San Lorenzo in the end of the episode. In real life there is no such country in Europe.
Part of the episode was shot at Portland State University, Portland, Oregon.
